Variables are data storage in C++, and there are around 8 different types(I think). I will only show the most basic 3 types, because I dont want to open up Code::Blocks to tell the fourth one correctly.
Variable type #1[Int(integer variable)]
The variable type int is what you use when you want a program to hold a number value, for example

Code:

#includes <iostream>
using namespace std;

int main()
{
  int x;
  cout <<"enter a number" << endl;
  cin >> x;
  system("PAUSE");
  return 0;
}


Variable type #2[float]=
The variable type float is used when you want to have a number with decimal places, for example:

Code:

#includes <iostream>
using namespace std;

int main()
{
  float x;
  x = 1.235486;
  cout << "this is x " << x << endl;
  system("PAUSE");
  return 0;
}


Variable type #3[char(character variable) =
the variable type char is used when you want to hold letter values, and you declare the length like this:

Code:

#includes <iostream>
using namespace std;

int main()
{
  char x[128];//changing the number in the brackets changes the length
  cout << "enter your name. " ;
  cin >> x;
  system("PAUSE");
  return 0;
}


those are the three most basic types of variables in c++, they should be sufficient for most of your coding needs, in the next tutorial I will post up some starting code for a text based game, and show you how to add in music, along with posting up my own text based game which I sadly deleted the Code::Blocks project so I dont have it's source code anymore . anyways, have a nice day.

Elaboration on a few data types:

(int) Integer = are whole numbers and negative numbers

(float/decimal) Decimal = are real numbers, whole numbers, and negative numbers. Floats are decimals too but just smaller decimals, and decimals are from a very wide range. Best to use decimal over float for space purposes.

(string) String = hold line of text

(char) Character = holds single characters such as 'A' or 'a'

(bool) Boolean = true(1) or false(0), uses 1's and 0's to represent true or false. Binary consists of  two digits 1 and 0. Computer's run off of binary.
